Apologies, I missed -H so it should be:

sudo -u mythtv -H mythfilldatabase


Additionally, if your version of mythfilldatabase supports it (run 
mythfilldatabase --help to check), you may want to add parameter 
--no-allatonce after mythfilldatabase e.g.

sudo -u mythtv -H mythfilldatabase  --no-allatonce

This minimises memory usage, by only grabbing 1 days worth of data at a 
time.

Some xmltv grabbers default to allatonce which due to the way 
mythfilldatabase is currently implemented can use huge amounts of 
memory, many gigabytes, leading to performance and possibly xmltv 
grabber failure..
